问题 I want to store images in a database using sql but cant seem to get it to work: qry.SQL.Clear; qry.Sql.Add('update tbl set pic = :blobVal where id = :idVal'); qry.Parameters.ParamByName('idVal')._?:=1; .Parameters has no .asinteger like .Param has but .Param isn't compatible with a TADOquery - to workaround I tried: a_TParameter:=qry.Parameters.CreateParameter('blobval',ftBlob,pdinput,SizeOf(TBlobField),Null); a_TParam.Assign(a_TParameter); a_TParam.asblob:=a_Tblob; qry.ExecSql; This also

问题 In my first question I had an error and it has been fixed, but now there is no error but nothing happends.

问题 So I have a report that is being generated that contains parameters. ReportParameter cvrParameter = new ReportParameter("cvrParameter", companyCVR); ReportParameter companyNameParameter = new ReportParameter("companyNameParameter", company.CompanyName); ReportParameter companyAddressParameter = new ReportParameter("companyAddressParameter", company.Address); ReportParameter companyCityParameter = new ReportParameter("companyCityParameter", company.City); ReportParameter studentCityParameter =

问题 Inside my jenkinsfile I want to set multiple properties based on some dependencies. So in the top of my jenkinsfile I am setting my first parameter: properties([ parameters([ booleanParam( defaultValue: false, description: '...', name: 'parameters1' ), ]) ]) Some lines below I want to set another parameter if a condition is met if(awesomeCondition) { properties([ parameters([ booleanParam( defaultValue: false, description: '...', name: 'parameters2' ), ]) ]) } The problem I am now running

问题 Is it possible to disable a certain action parameter from retaining its value across requests? [HttpPost] public ActionResult MyAction(string value1, string value2) { if(value1=="hi") ModelState.AddModelError("value1", "Can't have hi"); //do stuff if(ModelState.IsValid) return RedirectToAction("Finish"); else return View() } [HttpGet] public ActionResult MyAction() { return View() } The view consists of a simple form with two input boxes (value1 and value2). Once submitted and validation

问题 I need to create an operator that accepts a double 'parameter'. myClass myobject(); double mydouble = 10000; mydouble += myobject; My operator: double operator+=(double value, const myclass& object) { value += object.value; return value; } The parameter value is being passed to the operator += as zero, even though mydouble is initialized to 10000. How do you create an operator that can accept the left operand as a parameter? 回答1: The correct prototype is the following: double& operator+=

问题 I'm having troubles returning a value of type "T". It's easier to show than to explain so here is the method: Protected Function GetElementValue(Of T)(ByVal nodeName As String, Optional missingIfNotExists As Boolean = True, Optional missingIfEmpty As Boolean = True, Optional ByRef defaultVal As T = Nothing, Optional maxLength As Integer = Nothing) As T 'Set up the node to get the value from Dim node = xmlRoot.SelectSingleNode(nodeName) Select Case True Case IsNothing(node) 'If the node is

问题 How can one initialize parameter type array in verilog where each of members are 32 bit hexadecimal notation numbers? I have tried the following but it gives me syntax error. parameter [31:0] k[0:63] = {32'habc132, 32'hba324f, ...}; I'm using latest version of iverilog for compiling. 回答1: On EDA Plyground The following example works using modelsim 10.1, the file has a .sv extension, causing it to be interpreted as SystemVerilog: module test; parameter [31:0] k [0:1] = {32'habc132, 32'hba324f}

问题 Unfortunately this mess works: Do you have suggestings for cleaning up this code: I'm trying to use a activerecord to compare two table columns, "needed" and "amount" then update a boolean column, depending on the returned data. Totally breaking do-not-repeat coding. def update @inventory = Inventory.find(params[:id]) respond_to do |format| if @inventory.update_attributes(params[:inventory]) unless @inventory.needed.nil? if @inventory.needed < @inventory.amount then @inventory.instock = true

问题 I want to call a method like this: signature: void Method(object a, object b, params LambdaExpression[] expressions); call: Method(a, b, x => x.A, x => x.B) Is it possible? Let's assume that the type of 'x' is a constant type. For example, if x => x.A and y => y.B were Funcs, they'd be Func<TType,*> , such that the params array always had the same type for TType , but the return value's type * could differ from element to element of the params array. That's why I had to choose something more
